From the IUCN Red List Species Account:


Range Description

This species is known from a number of localities in the Eastern Highlands and Chimbu provinces, in Papua New Guinea. Its altitudinal range is 2,000-3,100m asl. It probably occurs more widely than current records indicate.

Habitat and Ecology

It lives in montane rainforest in rugged mountains and can tolerate some habitat degradation. It is a terrestrial species and breeds by direct development.


It is one of the most common frogs where it occurs.

Population Trend


Major Threats

It is possibly threatened by logging in some parts of its range, though insufficient data are available. However it occurs in some inaccessible areas where it should be safe.

Conservation Actions

Its distribution, habitat requirements and abundance need to be properly documented. It occurs in Crater Wildlife Management Area.

Red List Status

Least Concern (LC)


Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km2, it is very common and reasonably adaptable with a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
